BAGKBOARD.

Specification of Letters Patent.

Patented Jan. 2;, 1912.

Application filed October 8, 1910. Serial No. 586,114.

To all whom it may concern:

' Be it known that I, JONATHAN B. Hon- TON, a citizen of the UnitedStates, residing at Elkin, in the county of Surry and State of NorthCarolina, have invented a new and useful Backboard, of which thefollowing is a specification.

It is the object of the present invention to improve generally theconstruction of back boards for telephones shown in my prior applicationfiled April 16, 1910, Serial No. 555,7 95, allowed May 21, 1910.

One of the primary aims of the present invention is to simplify andlessen the cost of manufacture of the device and render its embodimentin a telephone back board more ready of accomplishment than in the formof the invention shown in my aforesaid prior application.

In the accompanying drawings, Figure 1 is a perspective View of thatportion of the device which is applied to the wall or other support uponwhich the telephone is to be mounted. Fig. 2 is a similar view lookingat the rear face of a telephone back board and illustrating theembodiment of the in vention therein. Fig. 3 is a vertical sec-- tionalview through a portion of the wall or other support and the saidtelephone backboard.

In the drawings, the wall or other support is indicated by the referencecharacter W and the telephone back-board by the reference character B.In mounting the back board of the telephone'upon the wall, particularlywhere the wall is of plaster and the only support which is afforded thetelephone is in the nature of an ordinary mold ing strip, indicated bythe numeral 5, the second strip indicated by the numeral 6 is secured tothe wall transversely of the strip 5. For a purpose to be presentlyexplained, a number of supporting hooks are arranged upon the transversecleat 6 in spaced relation and in horizontal alinement, and each ofthese hook members includes a shank which is threaded and is indicatedby the numeral 7, and a head which is indicated by the numeral 8 andconsists of two oppositely vertically projecting arms.

The back board B of the telephone has its rear face recessed as at 9 andsecured upon the said face of the board over the recess is a plate 10.This plate 10 is formed with slots which are equal in number to and aredesigned to receive the hooks 8. Each of these slots includes avertically extending portion 11 having a lateral portion 12 extendingfrom its upper end and terminating in a notch 13. In forming the slot,the plate is properly slit and that portion of the plate formerlyfilling the space of the vertical portion 11 of each slot is struck inat right angles as at 14, these portions 14 projecting into the recess 9in the rear face of the back-board B.

I11 arranging the telephone upon the wall, it is first disposed with itshooks 8 projecting into the vertical portions 11 of the respective slotsin the plate 10, and the telephone is then lowered until the shanks ofthe hooks engage with the upper edges of the laterally extendingportions of the slots, after which the telephone is moved laterally tobring the notches 13 directly above the respective hook shanks and thetelephone is then slightly lowered so as to engage the hook shanks inthe said notches. The engagement of the shanks in the notches serveeffectually to prevent lateral movement of the telephone, which movementmust be had before the telephone can be dismounted from the wall, itbeing furthermore necessary to lift the telephone in dismounting it,until the hook shanks are out of engagement in the said notches.

From the foregoing it will be readily understood that while thetelephone may be readily mounted upon and dismounted from a wallcarrying the hook members 8, it will be firmly held and supported inplace.

WVhat is claimed is v In a telephone support, the combination with atelephone back board, of a plate secured over arecess in the board andformed with a number of slots each including a vertically extendingportion and a laterally extending portion, and a plurality of hooksadapted for attachment to a support and to enter the first mentionedportions of the slots and engage at their shanks in the latmy own, Ihave hereto affixed my signature eral portions of the slots, thematerial of in the presence of two Witnesses.

the plate bein struck up to form the Vertically extendi ng portions ofthe slots, the JONATHAN BLAIR HORTON 5 struck up portions projectingrearwardly Witnesses:

and into the recess. J. I. MYERs,
